Guess this is a bug?
Some times I click on a tool [or am navigating through the sub tool window] and my entire screen goes black! Pressing ESC key returns screen to normal.
Other times the tool options stick and do not disappear:
Sounds like a bug to me. I think we’ll need a little more information to reproduce this here.
Can you please run the SystemInfo command in Rhino, click Save and attach your SystemInfo.txt here?
Can you reliably reproduce this or does it appear random?
If you can reliably reproduce it, please walk me through the exact steps you took (or use command+shift+5 to record yourself doing it). If I can follow the exact steps and reproduce it here, we have a fighting chance of fixing it.
Thanks!
